The pair of support members 112 may be disposed on the back side of the base member 116.

  With the above configuration, the frame 110 standing from the floor is obtained. In addition, in this embodiment, although the case where the frame-shaped frame 110 was used as a support | pillar part was demonstrated, a support | pillar part is not limited to this. For example, the column part may be a plate-like member. Moreover, in this embodiment, although the case where the flame | frame 110 which becomes independent on a floor was used as a support | pillar part was demonstrated, a support | pillar part is not limited to this. For example, the column part may be fixed and stand between the floor surface and the ceiling, or may be fixed and stand on the wall surface.

  The shelf board 120 is supported by the frame 110 and has a mounting surface 124 on which an article is mounted. In the present embodiment, the shelf board 120 is supported by the base member 116 of the frame 110. For the shelf plate 120, for example, a highly rigid material such as metal, resin, wood, or the like is used.

  The top plate 130 is positioned above the shelf plate 120 and supported by the frame 110. The top plate 130 may include a horizontal plate member 132 and a support member 138. The horizontal plate member 132 may be arranged such that the lower surface thereof is substantially parallel to the mounting surface 124 of the shelf plate 120 or the upper surface of the shelf plate 140 adjacent below. The support member 138 supports the horizontal plate member 132. The support member 138 may be supported by the locking hole 113 of the frame 110. For the horizontal plate member 132 and the support member 138, for example, a highly rigid material such as metal, resin, or wood is used.

  In addition, in this embodiment, although the case where the some shelf board 140 was distribute | arranged between the shelf board 120 and the top board 130 was demonstrated, the display shelf 100 is not limited to this. For example, the single shelf board 140 may be arranged between the shelf board 120 and the top board 130, and the shelf board 140 may not be arranged.

  FIG. 2 is a side view schematically showing an example of the form of the display shelf 100. As shown in FIG. 2, the display shelf 100 includes a power cord 231 that electrically couples the external power source and the display shelf 100, a deployment member 240, and a pipe 280. The horizontal plate member 132 includes an upper surface 134 and a lower surface 136. Further, the horizontal plate member 142 includes a mounting surface 144 and a lower surface 146. The power cord 231 electrically couples the external power source and the display shelf 100. The pipe 280 supplies a working fluid for expanding the deployment member 240 to the deployment member 240. Further, the support member 112 and the connecting member 114 may be connected by a bolt 115.

  As shown in FIG. 2, the deployment member 240 is supported by the frame 110 above the article mounted on the mounting surface 144 or the mounting surface 124. For example, the deployment member 240 may be supported on the lower surface 136 of the top plate 130 or the lower surface 146 of the shelf plate 140. That is, the deployment member 240 may be supported on the frame 110 via the top plate 130 or the shelf plate 140.

  The deployment member 240 may be arranged to face the mounting surface 144 or the mounting surface 124. For example, the deployment member 240 supported by the lower surface 136 of the top plate 130 may be disposed so as to face the mounting surface 144 of the shelf plate 140 adjacent along the support column member 112. Further, the deployment member 240 supported by the lower surface 146 of the shelf board 140 adjacent to the shelf board 120 along the support member 112 may be arranged to face the mounting surface 124 of the shelf board 120. In other words, in the present embodiment, the display shelf 100 includes a set of deployment members 240 that faces the shelf plate 120 and the mounting surface 124, and a set of deployment members 240 that faces the shelf plate 140 and the mounting surface 144.

  The deployment member 240 has a bag shape, and expands toward the lower mounting surface 124 when the working fluid is filled therein. For example, the deployment member 240 supported by the lower surface 136 of the top plate 130 expands toward the mounting surface 144 of the adjacent shelf plate 140 along the column member 112. Further, the deployment member 240 supported by the lower surface 146 of the shelf board 140 adjacent to the shelf board 120 along the support member 112 expands toward the mounting surface 124 of the shelf board 120. The deployment member 240 expands and presses the article mounted on the mounting surface 144 or the mounting surface 124 toward the mounting surface 144 or the mounting surface 124.

  As the shape of the expanding member 240 in the expanded state, an arbitrary shape such as a spherical shape, a hemispherical shape, an oblong shape, an oblate spherical shape, a rectangular parallelepiped shape, a truncated cone shape, or a truncated pyramid shape can be adopted. In the expanded state, a recess may be formed near the center of the lower surface of the deployment member 240. The deployment member 240 may be folded and stored before the working fluid is filled therein. FIG. 2 shows a state in which the deployment member 240 is folded and stored.

  For the deployment member 240, for example, a material that can be used for an airbag such as a rubber-coated cloth, a silicon-coated cloth, or a non-coated cloth may be used. Further, the developing member 240 may be made of an elastic material such as silicon rubber. The deployment member 240 may be an example of a bag-like body that expands toward the mounting surface 124 when the fluid is filled therein. Further, when an elastic material is used as the material of the deployment member 240, the deployment member 240 may be an example of a bag-like elastic body.

  When an elastic material is used for the deployment member 240, the contact area between the deployment member 240 and the article displayed on the mounting surface 124 or the mounting surface 144 is smaller than when no elastic material is used for the deployment member 240. And can be protected more. Since the deployment member 240 is deformed according to the shape of the article, the deployment member 240 can be prevented from damaging the article. It can also be easily installed on existing shelves.

  In the present embodiment, when the deployment member 240 is supported by each of the plurality of shelf boards 140, that is, the display shelf 100 includes a plurality of deployment members 240 supported by the lower surfaces 146 of the plurality of shelf boards 140. Although the case has been described, the display shelf 100 is not limited to this. For example, the deployment member 240 may be arranged on some of the shelf boards 140 among the plurality of shelf boards 140.

  FIG. 3 is a rear view schematically showing an example of the form of the display shelf 100. As shown in FIG. 3, in this embodiment, a pipe 280 is connected to each of the deployment members 240. Although not shown in the drawing, in the present embodiment, inside the pedestal member 116, a gas cylinder that contains a gas such as compressed air, a valve that allows the gas cylinder and the deployment member 240 to communicate with each other, or An activation unit for controlling the open / close state of the valve is arranged. The pipe 280 connects the gas cylinder and the developing member 240 through the valve.

  FIG. 4 is a diagram schematically illustrating an example of the fall prevention device 200 provided in the display shelf 100. The fall prevention device 200 may be an example of a fall prevention device provided in the display shelf 100. FIG. 4 shows the fall prevention device 200, a horizontal plate member 132, a horizontal plate member 142 adjacent to the horizontal plate member 132 along the column member 112, and the display 10 mounted on the horizontal plate member 142. Both are shown. The display item 10 may be an example of an article. Hereinafter, the fall prevention device 200 will be described with reference to FIG. 4, taking the deploying member 240 disposed on the lower surface 136 of the horizontal plate member 132 as an example. FIG. 4 shows a state where the deployment member 240 is not expanded.

  In FIG. 4, only a partial configuration of the display shelf 100 is shown for the purpose of simplifying the description of the fall prevention device 200. However, as described with reference to FIGS. 1 to 3, the display shelf 100 includes four shelf boards 140 along the support members 112 of the frame 110 between the shelf boards 120 and the top board 130. A deployment member 240 is disposed on the lower surface 146 of each shelf board 140. The deployment member 240 disposed on the lower surface 146 of the shelf board 140 may have the same configuration as the deployment member 240 disposed on the lower surface 136.

  The fall prevention device 200 suppresses the display item 10 mounted on the display shelf 100 from falling from the display shelf 100 when, for example, an earthquake occurs. As shown in FIG. 4, the fall prevention device 200 may include an activation unit 202, a deployment member 240, a gas cylinder 250, a valve 260, a valve 270, and a pipe 280.

  The activation unit 202 opens the valve 260 when the occurrence of an earthquake is detected or when vibration is detected. The activation unit 202 may detect the occurrence of an earthquake by receiving a notification of the occurrence of the earthquake. The notification of the occurrence of an earthquake may be notified by wire or may be notified wirelessly. The notification of the occurrence of an earthquake may be an emergency earthquake bulletin. The starting unit 202 may be an example of a valve driving unit. The activation unit 202 may include a control unit 210, a receiver 220, an antenna 222, a power supply unit 230, and a power cord 231.

  The control unit 210 controls the operation of the activation unit 202. For example, the control unit 210 controls the activation unit 202 so that the valve 260 is opened when the activation unit 202 detects an earthquake or vibration. For example, when a signal indicating that the earthquake early warning has been received from the receiver 220 is input, the control unit 210 may generate a drive signal for opening the valve 260 and output the drive signal to the valve 260.

Accordingly, the activation unit 202 can open the valve 260 when the receiver 220 receives an earthquake occurrence notification such as an emergency earthquake warning. Since the starter 202 can detect the occurrence of the earthquake by the emergency earthquake warning, the valve 260 can be opened before the earthquake vibration reaches or before the earthquake vibration becomes intense. The controller 210 may be electrically coupled to the power supply unit 230 and supplied with power from the power supply unit 230.

  The receiver 220 receives a notification that an earthquake has occurred. The notification of the occurrence of an earthquake may be an emergency earthquake bulletin. The receiver 220 is connected to an antenna 222 that receives radio waves. When receiving the earthquake occurrence notification via the antenna 222, the receiver 220 may generate a signal indicating that the earthquake occurrence notification has been received and output the signal to the control unit 210. The receiver 220 may be electrically coupled to the power supply unit 230 and supplied with power from the power supply unit 230.

  The power supply unit 230 is electrically coupled to the control unit 210 and the receiver 220 and supplies power to the control unit 210 and the receiver 220. The power supply unit 230 may be electrically coupled to an external power supply via the power cord 231. The power supply unit 230 may include a secondary battery, a fuel cell, a generator, and the like. Thereby, electric power can be supplied even during a power failure.

  The gas cylinder 250 contains a pressurized working fluid. The gas cylinder 250 may be an example of a fluid container. As the gas cylinder 250, a commercially available high-pressure cylinder can be used. The working fluid may be a non-flammable gas, a less toxic gas, or a gas that is less corrosive to the deployment member 240, gas cylinder 250, valve 260, or pipe 280. The working fluid may be air, carbon dioxide gas or nitrogen gas. When air is used as the working fluid, it is low in toxicity and corrosivity and can be used safely. When a nonflammable gas such as carbon dioxide or nitrogen gas is used as the working fluid, it can be used more safely even when a fire occurs due to the occurrence of an earthquake.

  The valve 260 allows the deployment member 240 and the gas cylinder 250 to communicate with each other or shut off. The valve 260 may be an example of a fluid valve. The valve 260 may be in a closed state before the drive signal is input from the control unit 210. That is, the flow of fluid between the deployment member 240 and the gas cylinder 250 may be blocked. On the other hand, the valve 260 may be opened when the drive signal is input from the controller 210. That is, the developing member 240 and the gas cylinder 250 may be communicated. As a result, the working fluid is supplied from the gas cylinder 250 to the developing member 240, and the developing member 240 is filled with the working fluid.

  Valve 260 may be a solenoid valve or an automatic valve having a pneumatic or oil actuator. The valve 260 is not limited to a valve that adjusts the flow or flow rate of the fluid by the movement of the valve body, but has a sealing member that seals the flow path in the closed state, and the drive signal is input thereto. And the one that opens the sealing member. Thereby, the leakage of the working fluid from the gas cylinder 250 in the closed state can be suppressed.

  The valve 270 discharges the working fluid filled in the deployment member 240, the pipe 280, and the like. The valve 270 may be disposed on a part of the pipe 280. The valve 270 may be an example of a discharge valve. A commercially available valve can be used as the valve 270. The discharge valve may discharge the working fluid when the pressure inside the pipe 280 becomes larger than a predetermined pressure. Accordingly, the working fluid filled in the deployment member 240 is discharged, and the deployment member 240 is stored again on the lower surface 136 of the top plate 130 or the lower surface 146 of the shelf plate 140, whereby the fall prevention device 200 can be reused.

  With the above configuration, the fall prevention device 200 supplies the working fluid stored in the gas cylinder 250 to the deployment member 240 and expands the deployment member 240 when the activation unit 202 operates upon receiving the notification of the occurrence of the earthquake. . The deployment member 240 disposed on the lower surface 136 of the top plate 130 expands toward the mounting surface 144 of the lower horizontal plate member 142 when the working fluid is filled. Then, the display 10 mounted on the horizontal plate member 142 of the shelf board 140 is pressed toward the mounting surface 144 of the horizontal plate member 142. Thereby, it can suppress that the display 10 falls from the shelf board 140 at the time of the occurrence of an earthquake.

  When the fall prevention device 200 includes the receiver 220, the fall prevention device 200 can receive a notification such as an earthquake early warning and inflate the deployment member 240. Thereby, before the seismic wave arrives or at a stage where vibration due to the earthquake is weak, the deployment member 240 can be expanded to prevent the display product 10 from falling more effectively. Further, the fall prevention device 200 can press the display 10 against the mounting surface 144 of the horizontal plate member 142 until the working fluid is discharged from the valve 270. Even if it exists, the fall of the display article 10 can be suppressed.

  In the present embodiment, the case where an earthquake occurrence notification such as an earthquake early warning is received has been described as an earthquake occurrence detection method, but the earthquake occurrence detection method is not limited to this. For example, as another example of the method for detecting the occurrence of an earthquake, although not shown in FIG. 4, the activation unit 202 includes a vibration sensor that senses the vibration of the earthquake. Also good. Moreover, although this embodiment demonstrated the case where the starting part 202 received the notification of the occurrence of an earthquake and opened the valve 260, the operating method of the starting part 202 is not limited to this. For example, the activation unit 202 may be manually operated to open the valve 260.

  Further, in the present embodiment, a description will be given of a case where the fall prevention device 200 has a gas cylinder 250 that stores pressurized working fluid, and the deploying member 240 is expanded by supplying the stored working fluid to the deploying member 240. However, the method of expanding the deployment member 240 is not limited to this. For example, a gas generating material such as explosive may be burned or exploded based on a drive signal output from the control unit 210, and the deployment member 240 may be expanded by a gas generated by the combustion or explosion.

  FIG. 5 is a block diagram schematically illustrating an example of the power supply unit 230. The power supply unit 230 may include a conversion unit 232, a charging circuit 234, and a secondary battery 236. Conversion unit 232 converts alternating current into direct current when the external power supply is an alternating current power supply. The charging circuit 234 controls charging of the secondary battery 236. The secondary battery 236 is charged by being supplied with electric power from an external power source in normal times. Thereby, even if a power failure occurs when an earthquake occurs, power can be supplied to the control unit 210, the receiver 220, and the like. As another example of the power supply unit 230, a primary battery may be used.

  FIG. 6 is a cross-sectional view schematically showing an example of the valve 260. FIG. 6 shows the valve 260 in the closed state. The valve 260 includes a body member 262, a sealing member 264, and an electric heater 266. The body member 262 is disposed between the gas cylinder 250 and the pipe 280. The body member 262 has a flow path 261 connecting the gas cylinder 250 and the pipe 280 inside. Inside the body member 262, grooves 263 are formed on the inflow side and the outflow side of the flow path 261. The body member 262 may be made of metal.

  The sealing member 264 is disposed on at least a part of the flow path 261 and seals the flow path 261 in the closed state. The sealing member 264 hermetically seals the gas cylinder 250. The sealing member 264 may be a material that melts by heat, such as solder or resin. The sealing member 264 may be an example of a sealing material. An electric heater 266 may be embedded in the sealing member 264. One end of the electric heater 266 may be grounded through the body member 262, and the other end of the electric heater 266 may be electrically coupled to the power supply unit 230.

  When the drive signal is input to the valve 260 from the controller 210, the electric heater 266 generates heat, melts at least a part of the sealing member 264, and perforates the sealing member 264. As a result, the valve 260 is opened, and the deployment member 240 and the gas cylinder 250 are communicated via the pipe 280. The electric heater 266 may be an example of a perforated part.

  FIG. 7 is a cross-sectional view schematically illustrating an example of a process in which the developing member 240 described with reference to FIG. 4 develops. 7, as in FIG. 4, the fall prevention device 200 is mounted on the horizontal plate member 132, the horizontal plate member 142 adjacent to the horizontal plate member 132 along the column member 112, and the horizontal plate member 142. This is shown together with the display item 10. In FIG. 7, only a part of the display shelf 100 is shown for the purpose of simplifying the description of the fall prevention device 200, as in FIG. 4.

  As shown in FIG. 7, the deployment member 240 has a pressing surface 242 and a bent portion 244. The pressing surface 242 may be a surface that contacts the display product 10 in an expanded state. The pressing surface 242 may expand first from the peripheral edge 246 when the expansion member 240 is filled with the working fluid and expands. For example, when the deployment member 240 has a shape in which the vicinity of the center of the pressing surface 242 is recessed inward, the expansion member 240 expands first from the peripheral edge 246. In addition, the pipe 280 may be attached to the deployment member 240 so as to expand first from the peripheral edge 246. Thereby, it can suppress more that the display article 10 falls from the display shelf 100 at the time of expansion | deployment of the expansion | deployment member 240. FIG.

  A protective sheet 248 may be disposed on the pressing surface 242. The protective sheet 248 may be, for example, a silicon rubber sheet. Thereby, it can prevent that the pressing surface 242 contacts the display article 10 and is damaged. The bent portion 244 may be a fold when the deployment member 240 is folded. The deployment member 240 may be folded and stored so that the bent portion 244 is on the inside when stored.

  FIG. 8 is a cross-sectional view schematically showing an example of a state where the development member 240 described with reference to FIG. 4 is developed. In FIG. 8, as in FIG. 4, the fall prevention device 200 is mounted on the horizontal plate member 132, the horizontal plate member 142 adjacent to the horizontal plate member 132 along the column member 112, and the horizontal plate member 142. This is shown together with the display item 10. In FIG. 8, only a part of the display shelf 100 is shown for the purpose of simplifying the description of the fall prevention device 200, as in FIG. 4.

  As shown in FIG. 8, the deploying member 240 disposed on the horizontal plate member 132 expands toward the mounting surface 144 of the adjacent shelf board 140 along the column member 112, and the mounting surface 144 of the shelf board 140 described above. The article mounted on the board is pressed toward the mounting surface 144 of the shelf board 140. Thereby, the fall of the display goods 10 can be suppressed. Further, when the pressing surface 242 includes an elastic material such as silicon rubber, the pressing surface 242 can enter the gap between the display items 10, so that the contact between the display items 10 or the overturning of the display item 10 can be suppressed. .

  FIG. 9 is a diagram schematically illustrating an example of the fall prevention device 300. The fall prevention device 300 may be another example of the fall prevention device provided in the display shelf 100. FIG. 9 shows the fall prevention device 300 together with the shelf plate 120, the horizontal plate member 132, the horizontal plate member 142, and the display product 10. Hereinafter, the control method of the display shelf 100 will be described with reference to FIG.

  In FIG. 9, only a part of the configuration of the display shelf 100 is shown for the purpose of simplifying the description of the control method of the display shelf 100 and the fall prevention device 300. In addition, for the purpose of simplifying the description, a case where three horizontal plate members 142 are arranged between the shelf plate 120 and the horizontal plate member 132 will be described as an example.

  As shown in FIG. 9, the fall prevention device 300 includes an activation unit 302, a deployment member 342, a deployment member 344, a deployment member 346 and a deployment member 348, a gas cylinder 352, a gas cylinder 354, a gas cylinder 356 and a gas cylinder 358, and a valve 260. , A pipe 382, a pipe 384, a pipe 386, and a pipe 388 may be provided. FIG. 9 shows a state before the deployment member 342, the deployment member 344, the deployment member 346, and the deployment member 348 are expanded. In FIG. 9, a state in which the deployment member 342, the deployment member 344, the deployment member 346, and the deployment member 348 are expanded is indicated by dotted lines.

  The deployment member 342, the deployment member 344, the deployment member 346, and the deployment member 348 may have the same configuration as the deployment member 240. The gas cylinder 352, the gas cylinder 354, the gas cylinder 356, and the gas cylinder 358 may have the same configuration as the gas cylinder 250. Further, the pipe 382, the pipe 384, the pipe 386, and the pipe 388 may have the same configuration as the pipe 280. Therefore, description of these details is omitted. Although not shown in the drawing, a valve 270 may be disposed in each of the pipe 382, the pipe 384, the pipe 386, and the pipe 388.

  In the present embodiment, the developing member 342 is supported by the horizontal plate member 132 and connected to the gas cylinder 352 via the pipe 382. A valve 260 is disposed between the pipe 382 and the gas cylinder 352. The deployment member 344 is supported by the horizontal plate member 142 adjacent to the horizontal plate member 132 and connected to the gas cylinder 354 via the pipe 384. A valve 260 is disposed between the pipe 384 and the gas cylinder 354. The expansion member 346 is supported by the horizontal plate member 142 adjacent to the horizontal plate member 142 and connected to the gas cylinder 356 via the pipe 386. A valve 260 is disposed between the pipe 386 and the gas cylinder 356. The deployment member 348 is supported by the horizontal plate member 142 adjacent to the shelf plate 120 and connected to the gas cylinder 358 via the pipe 388. A valve 260 is disposed between the pipe 388 and the gas cylinder 358.

  The activation unit 302 includes a plurality of delay timers 312 and has the same configuration as the activation unit 202 except for controlling the open / close state of the valves 260 provided in the gas cylinder 352, the gas cylinder 354, the gas cylinder 356, and the gas cylinder 358, respectively. You can do it. The activation unit 302 includes a control unit 210, a receiver 220, an antenna 222, a power supply unit 230, a power supply cord 231, and a delay timer 312. When the activation unit 302 operates, the control unit 210 of the activation unit 302 sequentially expands the deployment member 342, the deployment member 344, the deployment member 346, and the deployment member 348 from the side closer to the horizontal plate member 132.

  The delay timer 312 is disposed between the control unit 210 and the valve 260 provided in each of the gas cylinder 354, the gas cylinder 356, and the gas cylinder 358, for example. For example, by adjusting the number of delay timers 312 provided between each of the valves 260 and the control unit 210, the control unit 210 outputs a drive signal until each of the valves 260 starts operating. You can adjust the time. For example, in the present embodiment, the number of the delay timers 312 increases in the order of the gas cylinder 352, the gas cylinder 354, the gas cylinder 356, and the gas cylinder 358, and thus the valve 260 is opened in this order.

  Thereby, even if the shelf board 140 is not firmly fixed to the frame 110, it is possible to prevent the shelf board 140 from falling off the frame 110 due to an impact when the fall prevention device 300 operates. For example, in this embodiment, after the deployment member 342 is expanded, the deployment member 344 is expanded.

  That is, in the state where the deployment member 342 supported by the horizontal plate member 132 fixed to the frame 110 expands and the display product 10 is pressed against the horizontal plate member 142 adjacent to the horizontal plate member 132, the horizontal plate member The deployment member 344 supported by the horizontal plate member 142 adjacent to 132 expands. When the deployment member 344 expands and presses the display 10 downward, an upward force is applied to the lateral plate member 142 adjacent to the lateral plate member 132, but the lateral plate member 142 is directed downward from the deployment member 342. Since the force is applied, the horizontal plate member 142 can be prevented from falling from the display shelf 100.

  FIG. 10 is a diagram schematically illustrating an example of the fall prevention device 400. The fall prevention device 400 may be another example of the fall prevention device provided in the display shelf 100. FIG. 10 shows the fall prevention device 400 together with the shelf plate 120, the horizontal plate member 132, the horizontal plate member 142, and the display product 10. Hereinafter, the control method of the display shelf 100 will be described with reference to FIG.

  In FIG. 10, as in FIG. 9, only a partial configuration of the display shelf 100 is shown for the purpose of simplifying the description of the control method of the display shelf 100 and the fall prevention device 400. Similarly to FIG. 9, the case where three horizontal plate members 142 are arranged between the shelf plate 120 and the horizontal plate member 132 will be described as an example.

  As shown in FIG. 10, the fall prevention device 400 is different from the fall prevention device 300 in that the order of expansion of the deployment member 342, the deployment member 344, the deployment member 346, and the deployment member 348 is controlled by the arrangement of the pipes. The fall prevention device 400 may include a deployment member 342, a deployment member 344, a deployment member 346, and a deployment member 348, a gas cylinder 250, a valve 260, and a pipe 480. FIG. 10 shows a state before the deployment member 342, the deployment member 344, the deployment member 346, and the deployment member 348 are expanded. In FIG. 10, the deployment member 342, the deployment member 344, the deployment member 346, and the deployment member 348 are inflated and indicated by dotted lines.

  As shown in FIG. 10, in this embodiment, the deployment member 342, the deployment member 344, the deployment member 346, and the deployment member 348 are connected to the pipe 480 in this order. As a result, when the activation unit 202 operates and the valve 260 is opened, the working fluid stored in the gas cylinder 250 flows in the order of the deployment member 342, the deployment member 344, the deployment member 346, and the deployment member 348. As a result, similarly to the fall prevention device 300, the deployment member 342, the deployment member 344, the deployment member 346, and the deployment member 348 can be sequentially expanded from the side closer to the horizontal plate member 132, and the shelf board 140 is attached to the frame 110. Even if it is not firmly fixed, it is possible to prevent the shelf board 140 from falling off the frame 110 due to an impact when the fall prevention device 400 operates.

  The method for expanding the deployment member 342, the deployment member 344, the deployment member 346, and the deployment member 348 in this order has been described with reference to FIGS. 9 and 10, but the method is not limited thereto. For example, in FIG. 9, instead of preparing the gas cylinder 352, the gas cylinder 354, the gas cylinder 356, and the gas cylinder 358 for the deployment member 342, the deployment member 344, the deployment member 346, and the deployment member 348, respectively, the deployment member 342, the deployment member 344, A valve for controlling the inflow of the working fluid may be provided between each of the deployment member 346 and the deployment member 348 and the valve 260 to control the opening order of the valves.

  FIG. 11 is a diagram showing the form of the auxiliary instrument 510 and how to use it. 9 and 10, the method of preventing the shelf board 140 from falling off the frame 110 in the order in which the deployment member 342, the deployment member 344, the deployment member 346, and the deployment member 348 are expanded has been described. The auxiliary instrument 510 fixes the shelf board 140 to the frame 110. Thereby, it is possible to prevent the shelf board 140 from falling off the frame 110 due to an impact when the fall prevention device 200, the fall prevention device 300, or the fall prevention device 400 is operated. The auxiliary instrument 510 includes an insertion member 512 and a pressing member 514 provided on the side facing the insertion member 512. The auxiliary instrument 510 is made of a highly rigid material such as metal, resin, or wood.

  The shelf plate 140 is supported by the frame 110 by inserting the locking portion 149 of the support member 148 into the locking hole 113 of the frame 110. A gap is provided between the locking hole 113 and the locking portion 149 so that the shelf board 140 can be easily mounted or removed. Therefore, the insertion member 512 of the auxiliary instrument 510 is inserted into the gap, and the support member 148 is fixed to the frame 110. At this time, the pressing member 514 presses and fixes the horizontal plate member 142 supported by the support member 148 toward the support member 148.

  With the above configuration, the auxiliary device 510 can fix the shelf board 140 to the frame 110. The shelf board 140 fixed to the frame 110 may be an example of a support portion. Further, the lower surface 146 of the horizontal plate member 142 of the shelf board 140 may be an example of a support surface.

  FIG. 12 is a diagram schematically illustrating an example of the fall prevention device 600. The fall prevention device 600 may be another example of the fall prevention device provided in the display shelf 100. FIG. 12 shows the fall prevention device 600, a horizontal plate member 132, a horizontal plate member 142 adjacent to the horizontal plate member 132 along the support member 112, and the display 10 mounted on the horizontal plate member 142. Both are shown.

  As shown in FIG. 12, the fall prevention device 600 includes an activation unit 202, a gas cylinder 250, a valve 260, a valve 270, a deployment member 642, a deployment member 644 and a deployment member 646, a pipe 680, a pipe 682, and a pipe 684. And a pipe 686. The fall prevention device 600 includes a deployment member 642, a deployment member 644, and a deployment member 646 instead of the deployment member 240. The fall prevention device 600 includes a pipe 680, a pipe 682, a pipe 684, and a pipe 686 instead of the pipe 280. It may have the same configuration as 200. Each of the deployment member 642, the deployment member 644, and the deployment member 646 may have the same configuration as the deployment member 240.

  In the present embodiment, the deployment member 642, the deployment member 644, and the deployment member 646 are arranged along the lower surface 136 of the horizontal plate member 132. The deployment member 642 and the deployment member 646 are disposed in the vicinity of the peripheral edge portion of the horizontal plate member 132. That is, the deployment member 642 and the deployment member 646 are arranged at positions facing the peripheral edge of the horizontal plate member 132. The deployment member 644 is disposed between the deployment member 642 and the deployment member 646.

  As shown in FIG. 12, the pipe 680 branches into a pipe 682 and a pipe 684 and is connected to the deployment member 642 and the deployment member 646, respectively. Thereby, the deployment member 642 is connected to the gas cylinder 250 through the pipe 680 and the pipe 682. The deployment member 646 is connected to the gas cylinder 250 via a pipe 680 and a pipe 684. The deployment member 644 is connected to the gas cylinder 250 via a pipe 680, a pipe 684, a development member 646, and a pipe 686.

  Each of the deployment member 642, the deployment member 644, and the deployment member 646, like the deployment member 240, is filled with a working fluid and expands when the valve 260 is opened. Compared with the case where the display product 10 is pressed by one expansion member 240, the display product 10 can be pressed uniformly by being divided into the expansion member 642, the expansion member 644, and the expansion member 646.

  Further, since the pipe 680, the pipe 682, the pipe 684, and the pipe 686 are arranged as described above, the deployment member 642 and the deployment member 646 expand before the deployment member 644. That is, in the present embodiment, the activation unit 202 deploys the deploying member 642 and the deploying member 646 disposed at a position facing the peripheral portion of the shelf board 140 at a position facing the central portion of the shelf board 140. It is inflated before the member 644. As a result, when the deployment member 644 expands, the deployment member 642 and the deployment member 646 expand, so that the display article 10 can be prevented from falling from the display shelf 100 due to the expansion of the deployment member 644.

  In addition, in this embodiment, although the method to control the order which expand | deploys the expansion | deployment member 642, the expansion | deployment member 644, and the expansion | deployment member 646 with the structure of piping was demonstrated, the said control method is not limited to this. For example, a configuration similar to that of the fall prevention device 300 may be adopted and controlled by the control unit 210.

  Further, in the present embodiment, the case where the deployment member 642, the deployment member 644, and the deployment member 646 are arranged along the length direction L of the horizontal plate member 132 has been described. However, the deployment member 642, the deployment member 644, and the deployment The arrangement method of the member 646 is not limited to this. For example, the deployment member 642, the deployment member 644, and the deployment member 646 may be arranged along the width direction W of the horizontal plate member 132, or may be arranged in a matrix on the lower surface 136 of the horizontal plate member 132.

  In FIG. 12, only a part of the display shelf 100 is shown for the purpose of simplifying the description of the fall prevention device 200. However, as described with reference to FIGS. 1 to 3, the display shelf 100 includes four shelf boards 140 along the column members 112 of the frame 110 between the shelf boards 120 and the top board 130. Similarly, the deployment member 642, the deployment member 644, and the deployment member 646 may be disposed on the mounting surface 144 of the shelf board 140 as well.
